Key points at a glance

According to the Swiss Federal Office for the Environment (FOEN/BAFU), the building stock is responsible for around 22 % of Swiss CO₂ emissions – the third-largest emitter after transport and industry. More efficient heating systems are a key lever on the way to Net Zero 2050.
Conventional heating systems react slowly to changing weather: too cool in the morning, too warm in the afternoon. IoT sensors, weather data and AI enable predictive, precise control – without any structural changes.
ECCO2 starts at the heating plant: IoT sensors in the apartments and a control unit in the boiler room connected via the Swisscom mobile network continuously adjust the heating behaviour to actual demand – including solar gains, cold snaps and foggy conditions.
On average 20 % less heating energy after only a few weeks – certified by the Swiss Federal Office for the Environment (FOEN/BAFU). Savings benefit tenants directly.
Particularly suitable for larger residential, commercial and administrative properties. Investments pay off within a few years, depending on the building.
Digital heating systems deliver sustainability data automatically – an advantage for owners facing growing ESG reporting obligations.

Markus Eberhard, CEO ECCO2, in the article

«It’s about non-invasive heating optimisation. Existing boilers, heat pumps or district-heating connections remain completely unchanged.» — Markus Eberhard, CEO ECCO2 Solutions AG

This statement captures the ECCO2 principle: optimise instead of refurbish. The existing heat generation stays in place – ECCO2 uses sensors and NARA AI to ensure it runs at the right time with the right output.

Voices from the ecosystem

«Viboo and ECCO2 are both designed for permanently used, larger buildings. They cannot be compared with simple solutions for single-family or holiday homes that primarily switch heating on and off.» — Res Witschi, Delegate for Sustainable Digitalisation at Swisscom

«Secure data transmission, data protection and trustful collaboration are essential here.» — Felix Wunderer, Head of IoT and B2B Mobile at Swisscom

Echo from the network
